Alec N. Salt, Ph.D. Collaborator:
The group at Washington University prepared some of the guinea pig and chinchilla specimens and performed quantitative analyses of the cochlea fluid volumes in a number of species. The volume data have been used for computer simulations of drug movements in the cochlear fluids by this group.
